I want to know which kind of coating adhesion test methods are suitable for cylinder bore? I found the bending method in the Internet search but I am not sure about...
Hi,
I have ground the crankshaft (material: VCN 150 with nitrided surface) of a linear reciprocating engine to remove its ovality. the minimum grinding depth was 0.01 mm and the maximum was 0.06 mm (0.05 mm ovality).
The engine documents claims that the non-uniformity of grinding depth results...

2-...
As I know, Cv is the capacity of a valve to pass water in GPM with 1psi pressure drop. so the Cv of a valve doesn't depend on the medium and fluid type (gas or liquid).
regarding this, can I use water to measure Cv of a Valve that will work to pass Air?
In other word, if I measure Cv of a valve...
